Communications-based learning technology is an area of educational research that seeks to use advanced communication systems to enhance traditional learning environments with tools that allow students and teachers to formulate and exchange ideas. Increasingly technologies such as Instant Messaging, and chat systems are being used for teaching. We present two novel communications-based learning systems, Mak-Messenger and Finger-Chat, specifically designed to assist in the teaching of signed languages to deaf and hearing students. By providing these examples of learning technologies specifically tailored to the deaf community, we hope to illustrate how advanced learning technologies may be used to address issues relating to the educational needs of the deaf.
